GameStop selling their own SIM cards

Dubbed GameStop Mobile, the new service is a mobile virtual network operator based on AT&T's spectrum and network.

For $55 a month, GameStop sells its own SIM cards and service that run on AT&T's network with unlimited voice and tiered data. For $20 you can get even more limited data and voice calls as part of a "pay-as-you-go" service.

The company has seen its share of struggles in the past years, as profits and revenues disappear. With e-tailers offering better prices and with gamers finally turning wise to GameStop's rip off for used game trade-ins, the company has had its issues remaining profitable.

For the time being, the move could lead to the retailer selling unlocked smartphones, as well, through a trade-in program similar to what it does with console hardware and used games.
